Looking great Ed!! Much better this update!

Nice job on the box as well as the other details. You've made a vast improvement to the kit supplied figures as well! Very nice!!
I might tend to agree with adding a little spinkle of finely sifted dirt (got any old nylon stockings hanging around?

) and diluted WG here and there. Not much, just break up the 'smoothness' a little.
Also (can I be a pain here?), I'd like to see more of an eye level (or just slightly higher) photo looking in the pit from the opening.
Keep me posted!
